8.5M full-text U.S. court opinions from 1658 onward to 26Q1. Case names, filing dates, citations, and ~86B characters of cleaned opinion text. One record per row in ready-to-import CSV format.
Overview
This dataset contains 8,507,968 full-text U.S. court opinion records spanning 38 decades of American jurisprudence, with the earliest opinion filed in 1658. Each record pairs the complete narrative opinion text with its case metadata, making the corpus suitable for legal NLP, language model training, citation analysis, and legal research applications. Opinion texts average roughly 10,000 characters (about 1,600 words), range up to 3.4 million characters for the longest opinions, and total approximately 86 billion characters of cleaned legal text.
Each record includes:
case_name — the name of the case
cleaned_text — full narrative opinion text, cleaned and whitespace-normalized
citations — the case's citations as reported
date_filed — filing date
citations_norm — normalized citation string for matching and deduplication
The data ships as a single UTF-8, RFC-4180 CSV (~81.5 GB) with a header row, exported directly from PostgreSQL for reliable reimport into any database or data pipeline. Every record contains non-empty opinion text — empty and whitespace-only entries have been excluded. Text fields preserve original paragraph structure (embedded newlines are properly quoted), and null values are distinguishable from empty strings on import.

Dimensions summary
This listing charges through a single Product Access dimension that grants you access to the dataset. You subscribe through a contract, and the charge appears on your regular AWS bill. The data delivers into your AWS account through AWS Data Exchange, with all historical and future revisions included. Pricing does not scale by data volume, users, or usage. One subscription covers the full corpus of 8.5 million court opinion records in a single CSV file. Standard AWS infrastructure charges for storage and transfer apply separately on top of the subscription.
Top-of-mind questions for buyers
One unit grants access to the full dataset: 8,507,968 full-text U.S. court opinions from 1658 through the first quarter of 2026. You receive one CSV file of about 81.5 GB with a five-column schema. The subscription also includes all historical and future revisions of the data.
No. The subscription is a flat contract charge that does not meter by record count, query volume, or users. Future revisions are included at no extra subscription cost. The only variable costs are standard AWS infrastructure charges, such as S3 storage and data transfer, which apply separately.
The data delivers through AWS Data Exchange directly into your AWS account. You accept the entitlement, then export the CSV to any S3 bucket you own in the same region, by click or API call. There is nothing to download over the public internet and no separate vendor account to create.
